SHUTTLE EMBROIDLERING IJJ'ACHINE.

Application led September 10, 1921;.

To all whom 'it may concern.'

Be it known that I, GorrwAL" Sirene, a citizen of the Republic of Saxony, residing at Plauen, in Saxony, have invented certain new `and use'tul Improvements in Shuttle Ilmbroidering Machines, of which the tollowing is a specification,

his invention relates to a device in shuttle embroidering machines destined to do away with the friction formerly existing between shuttle and shuttle path, and it also insures a very reliable loop-catching and consequently a safer fixing of the stitches; on the shuttle side than hitherto was possible.

The new and characteristic feature of the device consists in that the shuttles with the thread contained therein are shifted, not above the embroidering needles, but to and tro below the latter and are lying on their backs. The weight of the shuttle bodies, therefore, does not bear on the path as formerly and any wear ot the shuttles seems nearly completely excluded, thus enabling the manufacture i a lasting good product.

Besides this the introduction ot the shuttle point into the loop formed by the rocking movement of the needle-bar is facilitated. In the devices oi known construction the thread loops always were formed on the upper side ot' the needles and projected beyond the shuttle guide path Ytar enough to enable the introduction olEv the shuttle. As result the loops had a great tendency to tall down so that the shuttles then did not slide into the loops, but shot over them.

It', however, the shuttles are arranged in the position as stated above, the thread-loops will always hang down so that the shuttle will be sure to pass through it and missing will be absolutely impossible.

A; further disadvantage in the known construction is that the needle channels in the path of the shuttles easily fill up with waste or dirt and in that case the formation oit tho loops becomes almost impossible. But in the present construction the shuttle path is below the needle channel so that nothing can get into the needle channels trom above, and the latter are tree ot dirt or waste and remain so always.

In the accompanying` drawings an embodiment of my invention is represented, Fig. l being a cross-section and Fig. 2 a. iront view of the needle and shuttle arrangement of an embroidering machine.

Specification of Letters Patent.

Serial No. 499,858.

Similar to well known devices the introduction of the needle thread into the. tab-ric in the present device also is brought about by the embroidering needle 2 iiXed to the needle-bar l. At the back side ot the fabric a bar 4 is provided having needle channels 3 and below which the shuttles 5 reciprocate horizontally. rl`he bar a is connected to an angle bar 7 by means oil a stitch-plate 6 ei(- tending in the longitudinal direction of the machine. The shuttles are each placed in a shuttle trame or basket 8 iixed to a. slide: 9 in such a manner as to render replacement or exchange of the shuttle easy. The point of the shuttle rests on a linger l() projecting from and forming part ot the shuttle-basket 8, and the back ll olIA the shuttle is held by an annular projection l2. Both the arm 10 and the projection l2 are as shown joined to the slide 9.

To permit access tothe inspection hole .ll of the shuttle 5 the basket 8 is cut out at 15. The slide 9 is carried by the driving-bar lG adapted to move to and tro thus transmitting the reciprocating movements ot the latter to the shuttles.

What I claim and desire to secure by Letters Patent is l. In av shuttle embroidering machine, the combination with horizontally reciprocating needles and a bar having channels in iront ot said needles, of means reciprocating below the channels ot said bar horizontally and at a right angle to said needles and shuttles supported in said means to extend. longitudinally oit the path of said means.

2. In a shuttle embroidering machine, the combination with horizontally reciprocating needles and a bar having channels in front ot said needles, of means reciprocating horizontally below the channels of said bar at a. right angle to said needles including frames or baskets and a shuttle supported in said frame to extend longitudinally of the path ot said trames.

3. In a shuttle embroidering machine, the combination with horizontally reciprocat ing needles and a bar having channels in front of said needles, of :trames or baskets horizontally reciprocatinpat a right angle to said needles, a shuttle deposited in each of said frames to extend longitudinally of the path ot' the latter, each ot said frames having means to engage the point and back of a shuttle.

Il. ln a shuttle einbioideiing,` machine, the eornbinafion with horizontally reciprocating needles, and a bar having channels in iront of said needles, ol a dfi\fing bai' inoxfable horizontally at a right angle to said needles and frames supported on saidv bai to extend below said channels, a shuttle removably supported in each li'ame so as to Vlaee the underside of said ehannelled bar, each olf said 4"i'an1es being adapted to embrace the point and the beek of a shuttle.

5. n a shuttle enibi'oideilng niaehine, the combination 'with hoiizonally reciprocating needles, and a bar havingv channels in front of said needles, of a driving bai* inovable horizonally at a right angle to said needles, and iframes supported on said bai o extend below said channels, and a shuttle having an inspection hole and removably supported in each frame so as to aeethe underside of
